WATER-ELEVATING APPARATUS.

Specification of Letters Patent. Patented March 23, 1909.

Application mea August' 7, 190s. serial No. 447,407.

Be it known that I, JAMES S. LAWRENCE, citizen of theUnited States, residing at San Javier, Sonora, Mexico, have invented cer tain new and useful Improvements in Water Elevating Apparatus, of which4 the following is a specification. l

This invention relates to water elevatin apparatus particularly suchv as is designe for draining mines, but my improvements may be employed for elevating Water from various other places. L

The invention consists generally in forming the discharge duct of the usual force pumping1 apparatus into a Siphon, and providing t e 1scharge end of the Siphon with a valve for automatically controlling the disy charge endof the siphonin such manner as to prevent the entrance of lair into the siphon should the action of the ump fail to keep the Siphon properly supp led with-water, or shoul the pump cease to operate.

The invention further consists in certain novel details of construction and combinations and arrangements of. arts all as will be now described and pointe out particularly` in the appended claims.

In the accompanying drawings: Figure 1 is 'a diagrammatic sectional elevation illustrating awater elevating plant or system embodying the present invention. Fig. 2 is an ele* vation of the discharge end of the Siphon and the 'preferred' form of automatic valve controlling the outflow." Fig. 3 is a plan view of the valve and associated parts.

-Similar letters of reference in the several figures indicate the same arts. i

A shaft or mine-to b'e rained is indicated diagrammatically at A in Fig. 1 of the drawings and the discharge point for the water is indicated at B.y Inorder to be discharged from the mine orshaft, the-water must be elevated to a higher level than the discharge point, thus as shown, the mouth of the shaft A is the highest point intermediate the intakeor pump and the discharge o1' out-flow.

`Extending from the water level 'in the shaft u to the mouth of the shaft and down to the ischarge point is a' pipe or conduit C,

ofproper cross-sectional area to handle the desired quantity of water and at a proper intermediate point apump -D is located. This pump may, in accordance-with usual practice, be located in the shaft near theintake and is adapted to force the water up through Ithe pipe or conduit, but in accord- .tions,. im ose a I ance with the present invention it is relieved by the s'iphonic action of the u per end of the conduit, from the ywork of eiiavating the Water to a greater height than is necessary for the siphon to become effective. `Witliout some means, however, to controlthe out flow, the siphonic action would be ineffective or at best irregular and would, under ome condigreater load on the lpun'p than Wou d exist if no si hon were emp oye To overcome this vdifficu ty, I provide a valve by means of which, under all conditions', the

pipe or conduit maybe kept full of water V down Tto the out-How and at the same time a discharge aperture is provided which may be increased or diminished in size in accordance with the ow at any particular moment. This valve is preferably automatic in its action andy controlled byV the pressure of Water in the conduit in proximity to the discharge aperture. As illustrated, the valve is -a simple gate valve E, sliding in ways F formed on a head' or casin Gr secured to or forming the discharge en of the conduit. A branch pipe or conduit II leads from the main conduit C at a point above or in front of the valve to a tank or cistern KL The branch H preferably opens into the top of the conduit Cas shown in Figs. 2 and 3 and enters 4the tank at approximately .the same level, whereby the normal low water level in the tank Ais determined.

A float M is located in the tank and connected by meansof a leverl N and link O with the valve whereby as the water level rises in the tank owing to increased pressure in the main conduit, the float will rise and open the valve-and as the water level lowers by reason of the decreased pressure in the main conduit and consequent reverse flow of Water through the branch, the iioat will drop and close the valve more or less, thus the actual discharge opening is 'regulated properly to maintain the conduit full of water, down to the discharge opening and the siphonic action will continue with equal force regardless of any irregular action of the pump and withadapted to be regulated by hand so as to j permit a certain proportion of the water flowing into the tank to discharge, but it willbe understood that any well-knownconnectedwith its intake arranger-nent may bel employed for regulating the height towhich the water may rise .in the tank or for operating the valve through the medium of the flow of water in thedischarge leg of thesiphon.

I claim as my lnvention:

1. In a water elevating apparatus, the

Combination with a'conduit having its discharge end formed into la siph'on and its in- 10` 'olsiphonic action, of a pump connected with take end extended to a point below lthe'level the intake end for elevating-the water to the level 'of siphonicaction, a valve for regulat lng thesize of the dischar e a erture at the outiiow and means Where y t `e positioniof.

the' valve controlled by thewater Within 4the discharge leg of the Siphon.

, 2. In a` Water velevating apparatus, the

combination `with al conduit having its disduit above the valve andthe tank.

3. In a .waterelevating apparatus, the combination with a conduit havingits disa tank in which the valve is located .the valve, a iloat in the tank and connections between they lioat and valve whereby the size of the discharge aperture is regulated in accordance with the water level in the tank.

4. In a. water elevating apparatus, the combination with 'a conduit having its dis# charge end formed intoa Siphon and a pump connected with its intake end for elevating the water to the level of siphonie action, ol' a valve controlling" the size of the out-flow aperture of the siphon, a tank, a branch con.- nection between the conduit above the valve andthe tank, a supplemental discharge for the tank, a Vfloat in the tank and cimnections intermediate the l'loat and valve whereby the size of the discharge aperture is regulated in accordance with the Water level in the tank.

ln testimony whereof', l have hereunto subscribed. my naine.
